<br>
We have the following behaviour when storeAsBinary is enabled:<br>
- when an entry is added it is initially stored in binary format (byte[])<br>
- when it is read from an *owning node*, it is unmarshalled and the object reference is cached in memory together with the byte representation<br>
- the object reference is only cleaned up when cache.compact() is invoked explicitly<br>
<br>
Assuming a key is read uniformly on all the nodes, after a while the system ends up with all the entries stored twice: the byte[] and the object in unserialized form. Of course this can be mitigated by asking the users to invoke Cache.compact - but that's quite confusing and not very user friendly as the user needs to be concerned with memory management.<br>
<br>
Can anybody think of some reasons why the value is kept twice? I mean besides optimising for local gets, which I think is not a good enough reason given the potentially huge memory consumption and the complexity added.<br>
<br>
